Abstract (en)
[origin: EP0350697A2] Organic hydroxy compounds, preferably aromatic, are converted to carbonates by reaction with carbon monoxide and oxygen under pressure in the presence of elemental or chemically combined palladium, divalent or trivalent manganese, at least one tetraalkylammonium halide and at least one quinone, aromatic diol reduction product thereof or mixture thereof. The preferred species are palladium(II) acetate, manganese(III) acetylacetonate, tetra-n-butylammonium bromide and 1,4-quinone or hydroquinone.
